Cloud-based repository hosting service GitHub has addressed a high-severity security flaw that could have been exploited to create malicious repositories and mount supply chain attacks.
The RepoJacking technique, disclosed by Checkmarx, entails a bypass of a protection mechanism called popular repository namespace retirement, which aims to prevent developers from pulling unsafe repositories with the same name.
The issue was addressed by the Microsoft-owned subsidiary on September 19, 2022 following responsible disclosure.
RepoJacking occurs when a creator of a repository opts to change the username, potentially enabling a threat actor to claim the old username and publish a rogue repository with the same name in an attempt to trick users into downloading them.
